Eliminates Need For Custom Pistons. This set phaser limiters, with the proper tuning software, allow the OEM computer to independently control intake and exhaust centerlines to take full advantage of the benefits of Variable Valve Timing (VVT) when using aggressive aftermarket camshafts without the need to install custom pistons to eliminate valve clearance issues.

Phaser Limiter Kit 06 Mustang GT

I am not a mechanic and the bulk of my experience is very basic. That said, the directions for installing these limiters are good enough to complete the job by anyone. The toughest thing for me was removing ...
the cam gear without unwinding the spring. There are three tiny spot welds (so small you can barely see them) that holds the spring in place until the the timing chain is on the gear. MAKE SURE you use the tools in the cam installation for holding the phaser spring in place. $299 if one comes unwound,,,,ask me how I know. These things do what they say they will do. Also, make sure you use the timing chain tool to release the pressure from the tension bar on the timing chain. If you do not have the tool, do not attempt the install. It does what it is supposed to do so I give it five stars. I give American Muscle 10 stars.

at the instructions refer to a long bolt that acts as a post for the cam phaser spring’s J-hook , but actually at my 2009 GT car's engine cam pahaser there are two long bolts , the other one act as a tensioner for the spring, my question is if I should too to reposition the spring onto it as it was before, as a OEM way, or it have not funcion after the phaser limites are instaled?

What special tools would you use on a 2009 mustang, since the tools included doesn't work with 09-10.

Will this add horespower using stock cams? Or is this only needed when installing comp cams?

The Comp Cams Phaser Limiter Kit does not add horsepower, as its sole purpose is to eliminate piston-to-clearance issues with Comp Cams camshafts.

I noticed the product says 05-07 GT. My car being a 2008 GT, would I not need these? Or is there something else i should be looking for? I'm planning on installing the Mother-Thumper Competition cams soon and I'm trying to make sure I have everything necessary. Would you be able to shed some light on this mystery for me?

These Comp Cams Phaser Limiter Kit fit 2005-Newer Ford 4.6L/5.4L Modular 3 Valves, so this would absolutely work with your 2008 GT. Comp Cams specifies that this phaser limiter kit only works with the factory phaser, and will not function properly with aftermarket phasers. Additionally, you would also need the Ford Performance 3V Cam Phaser Bolts for the installation of new camshafts, and we would also recommend using a engine break-in oil to properly break in the camshafts.
Here is the link for the Phaser Bolts, as well as the break-in oil:

Bought the Comp Cam Phaser Limiter Kit for my 2005 Ford Mustang GT in order to install the Mothr Thumpr cams, also from Comp Cams. The Comp Cam Phasers are a must have product in order to install these cams, can't do it with out them. After the install, my car has been running great, wicked idle sound, but very smooth running. I highly recommend this product especially if it is required in order to do a cam install.

These are not exactly easy to install, if your phaser is old replace it first. I tried using a local part store phaser and it did not work the internal of the phaser is different. I had to purchase an original ford part.

Saved your self the headache of dealing with special pistons and worrying about clearance issues. This Phaser Limiter kit allows the stock ECU to control your variable valve timing with the proper tune.

Word on The Street

AmericanMuscle is always a great place to shop for my mustang. They give detailed information about the parts and if they fit or what they need in order to fit. It is also very helpful that they suggest accessories to go along with what you buy. For an example, I just bought a new exhaust system and they suggested new O2 sensors (or extenders) which wad needed since the other ones came up to short. I will always buy from AmericanMuscle and recommend them to other mustang enthusiasts.
